Abstract It is pointed out that observations of sodium in twilight must always be correeted for Rayleigh-scattered white light and that the presence of the Fraunhofer lines must be allowed for. Otherwise they will effectively subtract from the sodium scattering and give a low value of the line brightness, particularly in early twilight. It is likely that this effect will mask the one recently treated by Donahue (1956), even after corrections have been made as well as possible. In any case, a… CONTINUE READING
